如何解释gcc 通过这种配置，gcc -mfloat-abi=hard不仅将使用FPU指令来构建文件，而且还会将它们与相应的库链接，从而避免错误.

How to interpret the output of gcc -print-multi-lib With this configuration gcc -mfloat-abi=hard not only will build your files using FPU instructions but also link them with corresponding libs, avoiding "X uses VFP register arguments, Y does not" error.

gcc使用-print-multi-lib输出>此补丁程序和--with-multilib-list=armv6-m,armv7,armv7-m,armv7e-m,armv7-r,armv7-a,cortex-m7配置选项. 如果您有兴趣使用Cortex-A系列multilib支持构建自己的gcc，只需对没有任何补丁的任何arm*-*-*目标使用--with-multilib-list=aprofile配置选项(

The above-mentioned -print-multi-lib output produced by gcc with this patch and --with-multilib-list=armv6-m,armv7,armv7-m,armv7e-m,armv7-r,armv7-a,cortex-m7 configuration option. If you are interested in building your own gcc with Cortex-A series multilib support, just use --with-multilib-list=aprofile configuration option for any arm*-*-* target without any patches (at list with gcc-6.2.0).
